Which modules of OpenStack are used to perform actions to achieve autoscaling and fault-tolerance?
I know that Heat (with Ceilometer) achieves this through given templates.

My doubt is if even Nova does automatically something like:

 "O gosh, that machine is exploding!  
 The workload is to high!  
 Let's launch another VM to share the load!"

or not.

I ask you this 2 main reasons:

  • I'm trying to understand if OpenStack has already a built-in MAPE cycle (Monitoring Analysis Planning Execution), or if it relies only on Heat templates;
  • I'm trying to understand if OpenStack isolates all the "adaptive" and "automatic" part into Heat, leaving Nova only as e mere executor of actions (launching, stopping and so on).

I hope that now the question is clearer.
Thank you

You might also want to look at Network Function Virtualization. While it is more of an architecture and not yet an implementation, more of MAPE functionality has been included in the NFV architecture. How much of NFV will be mapped directly to OpenStack is not an answered question yet.

I cannot see the link between MAPE and NFV.
Can you link me something to better understand what you mean?

Take a look at the MANO part of NFV: MANO draft. See section 4.5.1 for an overview, and section 7 for interfaces. It's just an architecture, but may have good thesis material.
